Introducing our Mandalorian left leg form made from urethane rubber.
This form is designed to provide a permanently screen accurate shape which includes the textured band seen on the original Mandalorian costume.
All the details will remain firmly in place, no matter how many bounties you hunt down!

The forms are produced in durable Shore 85 A Rubber (shoe heel equivalent) and will fit a calf up to 45cm around the widest point.
Slightly larger measurements can be accommodated but there will be a gap which would need to be bridged with extra leather.
For smaller sizes simply cut down equally on both edges of the form to fit.

This design was undertaken by us at JJ Industries with some support from Great Ape Studio for the textured area.

The part itself is approx. 29cm tall - however when finished the leather will hang below making the total length longer once complete.
The rubber itself is approx. 3mm thick, and the part weighs approx. 400g.

Please note: A-Grade forms are custom made to order, therefore will be subject to current custom order lead times. B and C grade forms when available for purchase will ship within 1-2 weeks.


Leg form can also be used as a stress toy...

Preparation & Notes

  • Each rubber form will arrive rolled wrapped in cling film/plastic wrap. The form can be rolled back on itself to help relax it out to it's full size. Once the leather is applied any small distortions should subside, gentle heat can also be applied to help reform the part. 
  • The inside surface will be slick to the touch from the molding process and release agents. We strongly recommend this surface be cleaned thoroughly with dishwashing detergent and hot water before use.
  • We recommend contact cement, barge or similar adhesives when working with the urethane rubber form. The diagram below covers the related dimensions for use with this form.

Knee Tab

This is an additional extra for anchoring knee armour to the shin in the instances of pre-beskar costumes - as per the original.


Selecting a grade above will provide a visual example of what to expect for each grade of shin form.

A Grade

  • Free from large voids 
  • Free from major defects
  • Fully intact product

B Grade

  • Central textured area intact 
  • Edges are mostly intact
  • May feature open areas and holes but these would not majorly impact the finished assembled part
  • This option is only available as rejections from the production process occur and cannot be made to order - if it is listed as out of stock then there are none currently available to sell

C Grade

  • Texture area intact 
  • Edges are missing or largely underfilled
  • This option is only recommended if buyers accept that only the textured section is intact
  • This option is only available as rejections from the production process occur and cannot be made to order - if it is listed as out of stock then there are none currently available to sell

    The silicon mold is so easy to use to make your leg wrap! The detail is amazing and combined with the knee armor/ shin tab, you cannot go wrong. This is the way
